looks really good,keep up the good work

 

I really like that setup. What fuel cell did you and racer go with?

 

I'll be running a custom made one and mount the factory sending unit in it to allow my stock gas gauge to work. Upgraded pumps of course.

 

I made mine, couldn't find the right size. GMracer I found out the hard way that the truck's fuel gauge is 40-240 ohm not the traditional chevy 0-90 ohm. I went with an Aeromotive A-1000 pump.
By the way anyone need a tube type 0-90 sender?

 

Is the stock truck 240 ohms empty, 33 ohms full?

 

no it's 250 ohm full , 40 ohm empty. Unfortunatly the aftermarket senders are reveresed from that! I'm working on a fix right now. I think if the resisters are reversed on the board it'll work............. I'll get back wid ya.

 

For the record, leave the resistors where they are. What needs to be done is move the neg terminal contact from the top of the board to the bottom with a jumper wire. One other thing to note is don't ground the aftermarket sender, theres two factory leads for the fuel gauge use them on the sender terminals and it doesn't seem to matter which is which it still works.
